ASX selects distributed ledger technology to replace CHESS

07 December 2017

ASX selects distributed ledger technology to replace CHESSASX today announces its intention to replace CHESS using distributed ledger technology (DLT) developed by its technology partner Digital Asset (DA).CHESS (Clearing House Electronic Subregister System) is the system used by ASX to record shareholdings and manage the clearing and settlement of equity transactions in Australia. It was world-leading when introduced in the 1990s, providing name-on-register functionality, electronic communications and removing paper share certificates. It continues to be a robust and reliable system. ASX is now taking the opportunity to replace CHESS with a next generation post-trade platform using contemporary technology.Today's decision follows the successful build of enterprise-grade DLT software for core equity clearing and settlement functions, and the completion of extensive suitability testing by ASX and DA over the past two years. The testing confirms ASX's confidence in the functional, capacity, security and resilience capabilities of DA's application of DLT to meet the needs of Australia's financial marketplace and maintain the highest regulatory and operational standards. The testing included two independent third party security reviews of DA's technology.
